prepare-task-for-implementation-approval

This skill is mandatory as part of the plan-task workflow. It is not independently optional when plan-task is in use.

Before work: read ../plan-task/SKILL.md, follow all files it requires, and apply the full plan-task bundle as shared convention guidance. Then read implementation-approval-guidance.md.

Update the same active task artifact for implementation-approval readiness. Do not create a second task artifact or a new pre-implementation task status.

Use implementation-approval-guidance.md as the authoritative source for readiness checks, diagram-first preparation, duplication removal, and approval-seeking output.
